Freedom of speech advocate Howard Stern may have to put his money where his mouth was, as CBS Radio has slapped the King of All Media with a massive lawsuit. Among other things, the 43-page complaint alleges that Stern used his final months of terrestrial-radio airtime to pimp his new Sirius Satellite gig, which in essence helped him reap a $220 million stock-option windfall once Sirius added enough new subscribers. "CBS Radio is going to have an uphill battle to win this," a former SEC attorney tells Variety. "CBS tried to take advantage of the publicity surrounding [Stern's] move, so it's going to be hard to argue they were... defrauded." One significant legal issue this suit will raise is whether strippers need to wear pasties when testifying in court.
